Description
Beim Erwärmen von Flüssigkeiten durchDampf-, Gas- und Flüssigkeitsbeheizung bilden sich oftmals an den Heizflächen Verkrustungen, welche die Wärmeübertragungen stark beeinträchtigen und auch oft eine Verfärbung der Flüssigkeiten verursachen.When heating liquids by steam, gas and liquid heating Encrustations often form on the heating surfaces, which prevent the heat transfer and often cause discoloration of the fluids.
Dieser Übelstand kann dadurch beseitigt und die Wärmeaustausch- bzw. Heizflächen dadurch von den sich bildenden Krusten befreit werden, daß die Heizwände, von denen die eine Seite beheizt und die andere Seite flüssigkeitsbenetzt ist, wechselweise für Beheizung .und Wärmeabgabe umschaltbar eingerichtet sind. Von wesentlicher Bedeutung ist dabei der Umstand, daß die Durchströmverhältnisse durch die Heiz- bzw. Erwärmungsräume gleich oder nahezu gleich gehalten werden, um das Abspülen der Krusten von der Flüss@igkeitserwärmungsfläche mit Sicherheit zu erreichen.This deficiency can thereby be eliminated and the heat exchange resp. Heating surfaces are freed from the crusts that form by the fact that the heating walls, one side of which is heated and the other side is wetted with liquid, alternately for heating and heat emission are switchable. Essential is the fact that the flow conditions through the heating or heating rooms be kept the same or nearly the same to prevent rinsing of the crusts from the liquid heating surface to achieve with certainty.
In der Zeichnung werden fügf Ausführungsformen dieser Wärmeaustauscher veranschaulicht, und zwar wird in Abb. i und 3 der Mantel durch zwei in Rohrböden eingewalzte oder sonstwie eingespannte zylindrische Rohre gebildet, wogegen in :11>b. 2 der Mantel aus viereckigen und in Abb. 5 aus sechseckigen Rohren besteht, deren Enden unter Wegfall der Rohrböden miteinander verschweißt sind. In Abb. 4 wird dagegen der Mantel aus den Wellen zweier benachbarter Wellbleche geformt.In the drawing, embodiments of these heat exchangers are illustrated, namely in Fig. I and 3 the jacket is formed by two cylindrical tubes rolled into tube sheets or otherwise clamped, whereas in: 11> b. 2 the jacket consists of square tubes and, in Fig. 5, of hexagonal tubes, the ends of which are welded to one another, eliminating the tube sheets. In Fig. 4, however, the jacket is formed from the waves of two adjacent corrugated sheets.
Wie ersichtlich, kann der Mantel, aber auch das Innenrohr eine beliebige Form erhalten. Das Wesentliche dieser Heizkörper ist, daß die Heizrohre von Mantelrohren umgeben sind, deren Bemessungen derart gehalten sind, daß der Querschnitt des Raumes des Innenrohres und der Ringraum zwischen Innenrohr und Mantel etwa gleich sind, um eine gleiche Geschwindigkeit für den Dampf auf beiden Seiten der Heiz"vand zu erhalten.As can be seen, the jacket, but also the inner tube, can be any Maintain shape. The essence of this radiator is that the heating pipes of jacket pipes are surrounded, the dimensions of which are kept such that the cross-section of the room of the inner pipe and the annular space between the inner pipe and the jacket are roughly the same, in order to have an equal speed for the steam on both sides of the heating "vand too." obtain.
Abb.6 zeigt die Anbauweise der Wärmeaustauscher als Heizkörper bei einem Verdampfer. Durch entsprechende Einstellung der Absperrorgane werden die zu erwärmende Flüssigkeit und das Heizmittel wechselweise mit beiden Seiten der Heizwand des Wärmeaustauschers in Berührung gebracht, wobei etwa entstandene Verkrustungen von dem Heizmittel durch Abspülen von der Heizwand entfernt werden, so daß eine Verminderung der Heizwirkung ausgesClialtet wird.Fig. 6 shows how the heat exchanger is installed as a radiator an evaporator. By setting the shut-off devices accordingly, the to heating liquid and the heating medium alternately with both sides of the heating wall of the heat exchanger brought into contact, with any resulting incrustations be removed from the heating means by rinsing from the heating wall, so that a Reduction of the heating effect is withdrawn.
